Abstract

A bicycle racing shoe equipped with a second sole, more or less the samewidth and the same length as that of the shoe on which it is screwed on atthe middle and at the rear of same, and whose front bends downward during theupward movement of the leg.<IMAGE>

Description

       

   <Desc / Clms Page number 1>
 



  The present invention relates to a cyclist running shoe.



  Modern cycling shoes, currently on the market, are equipped with automatic pedals which allow cyclists to pull on them during the rising movement of the leg.



  The pedals located at the tip of the shoe are distant from the ankle, therefore cantilevered from the latter and make it provide an effort which prevents the maximum efficiency of the traction effort provided by the cyclist during the upward movement of the leg.



  The present shoe has received an additional component which is the subject of the invention.



  This additional component consists of a second sole, preferably made of plastic, more or less the same length and width as those of the shoe where it is attached, in the middle and at the back thereof, having the possibility of deforming longitudinally and downward in its front part when it is stressed by the upward movement of the leg.



  The wedge usually attached to the shoe is fixed at the same height, under the second sole.



  This second sole, when it deforms downwards due to the action of the upward movement of the leg, pulls on the central fastener of the shoe, the upper part of which rests on the top of the kick.



  The shoe thus constructed allows the cyclist to lift the pedal with the top of the kick instead of pulling it with the tip of the foot. tiptoe.



  The point of traction being closer to the ankle, it will be less stressed and the speed of the cyclist will be increased in the hills and during sprints or violent efforts.



  The shoe and its component will be described below and illustrated by the drawing.

  The drawing shows the ascending pedal and the descending pedal.



  The shoe has an additional component which is a second sole 1 which can be made of plastic.



  This sole is attached to the rear of the shoe by a screw and another 3 located approximately in the middle of the sole 1 and below the kick.



  At the front of the sole 1, there is the shim 2 on which the automatic pedal 6 is clipped.



  When the cyclist pulls the pedal up, the front of the sole 1 deforms down, causes a spacing 2 which acts on the screw 3 which pulls the middle of the shoe down and the upper part of which this comes to press the kick 4 of the cyclist.



  The traction point & which is at the level of the axis of the pedal is then moved to kick 4.



  During the downward phase, the spacing 2 disappears and the sole 1 is replaced against the sole 9 of the shoe.


    

Claims (1)

Claim Cycling shoe fitted with a second sole 1, made of a flexible material, more or less the same length and the same width as that J? of the shoe to which it is secured by two fasteners: one in the middle 3, the other 2 at the rear, the front of which, designed to receive the cleat 5 of an automatic pedal 6, can deform towards the down when the shoe is pulled up by the upward movement of the leg.
